即使实现了addSkipBackupAttributeToItemAtURL,仍然可以备份到iCloud？

Question

我最近的iOS应用程序刚被拒绝,因为应用程序将数据存储在Documents上,因此它由iCloud备份,因为数据是从服务器下载的,所以不允许这样做.

我正在尝试重建代码,并且在将数据存储在文件夹中时遇到了困难,而不是将应用程序支持调用.

但即使我正在使用addSkipBackupAttributeToItemAtURL,它仍然显示为iCloud的备份.

我只针对5.1,因此它不是版本问题.

我在下面添加了受影响的代码:

    NSString *newPath = [NSMutableString stringWithFormat:@"%@/Library/Application Support/", NSHomeDirectory()];

    if (![[NSFileManager defaultManager] fileExistsAtPath:newPath]) //Does directory already exist?
    {
        if (![[NSFileManager defaultManager] createDirectoryAtPath:newPath
                                       withIntermediateDirectories:NO
                                                        attributes:nil
                                                             error:&error])
        {
            NSLog(@"Create directory error: %@", error);
        }

    }

    NSString *guidesPath = [newPath stringByAppendingPathComponent:@"/Guides"];
    if (![[NSFileManager defaultManager] fileExistsAtPath:guidesPath])  //Does directory already exist?
    {
        if (![[NSFileManager defaultManager] createDirectoryAtPath:guidesPath
                                       withIntermediateDirectories:NO
                                                        attributes:nil
                                                             error:&error])
        {
            NSLog(@"Create directory error: %@", error);
        }

    }

    NSString *dataPath = [guidesPath stringByAppendingPathComponent:dbName];

    if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
    {
        if (![[NSFileManager defaultManager] createDirectoryAtPath:dataPath
                                       withIntermediateDirectories:NO
                                                        attributes:nil
                                                             error:&error])
        {
            NSLog(@"Create directory error: %@", error);
        }

    }

    NSString *newGuidesPath = [dataPath stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    NSURL *guidesURL = [NSURL URLWithString:newGuidesPath];
    [self addSkipBackupAttributeToItemAtURL:guidesURL];

    NSString* path = [dataPath stringByAppendingPathComponent: 
                      [NSString stringWithString: finalName] ];
    if (![fileManager fileExistsAtPath:path]) {
        [myData writeToFile:path atomically:YES];
        NSString *docFile = [dataPath stringByAppendingPathComponent: @"guideid.txt"];
        [[guideID dataUsingEncoding:NSUTF8StringEncoding] writeToFile:docFile atomically:NO];
        DLog(@"Saved database here:%@", path);
    }else{
        DLog(@"Already exists, no need to copy");
    }

}

 - (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{


assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]);

NSError *error = nil;
BOOL success = [URL setResourceValue: [NSNumber numberWithBool: YES]
                              forKey: NSURLIsExcludedFromBackupKey error: &error];
if(!success){
    NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error);
}

return success;
}

实际上找到了一个解决方案,我编写了不需要的URL.刚刚将其添加到文件夹中

    NSURL *guidesURL = [NSURL fileURLWithPath:guidesPath];
    [guidesURL setResourceValue:[NSNumber numberWithBool:YES] forKey:NSURLIsExcludedFromBackupKey error:NULL];

并跳过了exclude方法,只是在代码中标记了它,这似乎有效.
